ID tip

The bay-chested warbling finch is a rather dainty, warbler-like finch, measuring 13.5 cm long on average and with an average weight of 11–12.8 g. Males have gray upperparts, getting progressively browner from the head to the tail. The grayish upper-wing displays a white flash when the wings are closed, created by the white edges and bases of the outer primaries. The anterior edge of the wings is also white due to the white marginal coverts. The throat, cheek, and underparts are also white, interrupted by a bright reddish-brown breast-band stretching along the sides to the flanks.
